如何通过单个 resex 验证电子邮件和 phone 号码？

Question

好吧，我有 2 个单独的正则表达式用于验证电子邮件和 phone 号码。喜欢

email = "^\w+\@([\da-zA-Z\-]{1,}\.){1,}[\da-zA-Z-]{2,6}"

和

phone = "^[2-9]\d{2}-\d{3}-\d{4}"

但是，我想输入一个字段，可以是电子邮件和 Phone。我必须验证它们。我试过使用 ||这两个 resex 或之间的运算符，但没有用。

[Required]
[MaxLength(50)]
[RegularExpression(@"^\w+\@([\da-zA-Z\-]{1,}\.){1,}[\da-zA-Z-]{2,6} || ^[2-9]\d{2}-\d{3}-\d{4}$", ErrorMessage = "Invalid Phone number Email Address")]
[Display(Name = "Phone number or Email")]        
[System.Web.Mvc.Remote("IsUserExists", "Account", HttpMethod = "POST", ErrorMessage = "This Phone number or Email already exists")]
public string MobOrEmail { get; set; }

所以我需要一个合适的正则表达式，它可以同时验证电子邮件或 phone 号码。或者它们之间的 or 操作将是完美的，我非常需要它。谢谢

您需要一个 |（竖线）字符（不是 2 个）并且没有空格。应该是

[RegularExpression(@"^\w+\@([\da-zA-Z\-]{1,}\.){1,}[\da-zA-Z-]{2,6}|[2-9]\d{2}-\d{3}-\d{4}", ErrorMessage = "...")

参考regexr

请注意，您的电子邮件正则表达式不是很强大。 jquery.validate.js使用的是

/^((([a-z]|\d|[!#$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))$

为了使其在模型中更易于阅读并更易于重用，您可以创建自己的扩展 ReqularExpressionAttribute

的属性

[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field, AllowMultiple = false)]
public class EmailOrPhoneAttribute : RegularExpressionAttribute
{

    public EmailOrPhoneAttribute () : base(@"^\w+\@([\da-zA-Z\-]...etc")
    {
        // Add default error message
        ErrorMessage = "Invalid Phone number Email Address";
    }
}

并在global.asax.cs

中注册

protected void Application_Start()
{
    ....
    DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(EmailOrPhoneAttribute), typeof(RegularExpressionAttributeAdapter));
    ....
}

然后在模型中

[EmailOrPhone]
public string MobOrEmail { get; set; }
